IMPROVEMENT IN BOOTS AND 53023..

The Schedule inferred to in than Letters -P titent and making put of the limb To all whom it may concern: c

lle it known that I, Amumwncm of "the city otNew York, county and. State of New York', have invented. a new and useful. Improvement in- Boots,

Shoes, and Lasts; and I do hereby declare that l the v following is a full. and cxaet'description' thereof, refetten'ce being bad the' aceoi'nln nying drawings and mule-me of leterence'marsed thjereomin 'which-.

Figurelis an elevation ota last, formed in accord aneewithmyluvention} F gure .2 is a view of theu'nde'r side of the; same; Figure 3 is a view of a shoe made-accordingfto my .inveqtiongaml t Figure 4 is ascctiomof thesaine, showing the position of the foot within theshoe;

The nature of my invention consists in providing a concavity .or-hollow in the insole of the hoot or s oe, immediatelyunder the arch or hollow of thefoot, by which the concave surface of the arch of the foot is prevented from pressing against the-insole of the boot or shoe, and the importantnervesconcentrated in the hollow of the'lhot are thus relieved from injurious pressure. .I'nnihc mylast in the usual way, except the shank or hollow lying between the heel and the ball, which part I cause to project beyond the line of the heel and ball, so asto i'orm'a. ridge, extending from homediately front of tl|e.l1eei; and terminating near the ball, as'sliown in figs. 1 and 2.

Iron the last 1 tiisteu theinsole in the usualway', and shavc it down immediately ov'erthc projectionfB, so that the ontside'solc will lit, and the external appearance of the boot or shoe, when finished, will not bqdnatci'inlly dillerent from those commonly worn {or a shoe constructed according to I may make the shoe upon a common last, having;' the insole composed of three or more pieces, the center piece, under the arch of the foot, beingremovable when the shoe is finished. r i 1 lntfigql the part A is similarto a common last. The addition 13 is themodification involved in' this invention. It-is an oblong swellitzg projection, as seen infig. 2, and may he made solidnvith the last, or it ay be added by any ordinary means to lasts already in use. u 1

Fig. 3 shows a shoe, A, made according-to this intent-ion, with the part Bf, forming the subjectof this improvement, shown on a somewhat exaggerated scale; a V r Fig; 4 shows the position-oi the human foot within this invention,- in which- Oisthefoot;- i Eris the ball of the foot 15' the hollow under the arch F; the heel; and. 1) shows the net-workot' important nerves concentrated in the hollow of the foot.

Having thus described myinvent'ion, \Vhat I claim as new,- and desire to secure 0y. Let- 'ters Patent, is-

1. The projectiug-pieee-or portion ll of the last-,as and for the purpose herein set forth.

2. The concavity or hollow B" in theboot or shoe,

as and for the nn-pose herein sot'fm-th;

ANDREW BURKE.
